I started an airlayer on 2 trident maples earlier this year. When I went to separate them 2 weekends ago I found that one had calloused over. I'll try to find the before pictures, but here it is after I cleaned it up and started the layer again.

(This tree will be pampered in a greenhouse after it loses its leaves to keep whatever gets growing before fall from dying.)

Just wondering how long the air-layer was on. I never tried a trident, but on a few good sized natal plum, I had many roots in 6 weeks. Do you think the rough bark from possible earlier branch removal at that spot had anything to do with it?Also , for future reference, when the air-layer is removed, will the base trunk be used also.

Was the other one a similar size, and did it have any old scars in the layer area..... any pics before you seperated the other one.I've not done air-layering before, but have done my first on a Japanese Maple about a month ago. Hoping for a good result.My guess , this one possibly dried out..... spaghnum moss wasn't kept moist enough. How long before you unwrapped it?
